I hear its around 800 milligrams per kilogram of body weight, I weigh 64 kg so its around 51200 g of acetaminophen to kill me, but small doses over a large period of time can cause severe liver damage.
The Tylenol bottles always say "It is hazardus to exceed 4,000mg (4 grams) unless advidesd by a doctor. So if you take say, 10,000mg (10 grams) you would probably have sever liver damage, or even worse, liver failure.
I believe the answer is 1.3 x 10^3 pills/hour.
As a toxicologist and medical student, i do not understand that answer so I'll add that
the drug databank (maintained via university of Alberta) lists it only for mice/rats but does report that liver failure in people(that would be fairly lethal, eh?) has occured at daily doses of 4000mg. Ld 50 mean some die early and others late as levels increase so fatal for some is maybe only moderate damage for others.
The LD50 of hydrocodone (Vicodin) is irrelevant because the amount of acetaminophen in the pills would kill you more quickly, and more horribly. The LD50 for acetaminophen, which can be between 90-99% of the Vicodin pill, has been estimated at ranges between 330 and 2000 mg/kg, although liver failure has been observed in adults at doses as low as 6 g (according to Canadian Drugbank website, linked below).
The previous poster's information is incorrect. The acetaminophen poisoning that would result would indeed be lethal, and horribly so, at a dose that would be lethal in terms of hydrocodone; however, the narcotic lethality of hydrocodone is MUCH faster than the liver toxicity of acetaminophen.
Oral LD50: 636mg/kg (rat), 740 mg/kg (mouse), 495 mg/kg (guinea pig).
See you Pawel
4.5 GRAMS/KG (That's 4500mg/kg) for a rat
1.85 GRAMS/KG (That's 1850mg/kg) for a mouse
Seems you'd be hard-pressed to die by way of overdose...

Why is the LD50 of a mouse different from a human's LD50?
ld50 for lamotrigine
True or False. Does a chemical with a LD50 of 1000mg over kg have less toxicity than one with LD50 of 100mg over kg?
True. The chemical with an LD50 of 1000mg/kg is less toxic than the one with an LD50 of 100mg/kg. LD50 is the lethal dose at which 50% of the test subjects die, so the higher the LD50 value, the less toxic the chemical is considered.
What is the ld50 of thiopental?

Why do cockroaches survive a nuclear bomb?
The radiation LD50 of most insects is far higher than the LD50 of mammals.
What is the LD50 of methanol for a 100 gram rat?
The LD50 of methanol for rats is typically around 5628 mg/kg. To calculate the LD50 for a 100 gram rat, you would multiply the LD50 value by the weight of the rat in kilograms (100 grams = 0.1 kg) to get an estimated lethal dose.
What is the LD50 standard?
1mg/kg
What is the LD50 value for plutonium?
A probable value for plutonium is LD50 = 5 μg/kg (cumulated chemical and radiological effects).
What is the LD50 of phenobarbital?
The LD50 of phenobarbital in humans is estimated to be around 15 mg/kg when taken orally. LD50 represents the dose at which 50% of the test population would die as a result of the substance.
10 rats given LD50 dose of aspirin how many rats survive?
by definition ld50 is when 50% survive or dead,,answer will be 5 if i count well
Why does Magnesium Sulfate not have an LD50?
Magnesium sulfate does not have a specific LD50 value because it is not regarded as acutely toxic in typical exposures seen in therapeutic applications. It is commonly used as a medication, mainly for maternal eclampsia and as a supplement to correct magnesium deficiency.
Is acetaminophen an ADHD medication?
No. Acetaminophen is Tylenol.
What is the margin of safety in LD50 200mg and ED50 60mg?
